OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 445,490, dated January27, 1891.

Application filed April 12 1890 To all whom it may concern:

Be it known that 1, CHARLES H. BAKER, of I he city, county, and State ofNew York, have invented a new and Improved Oil-Cup, of which thefollowing is a full, clear, and exact description.

The object of my invention is to provide a practical oil-cup designedmore particularly for wagon-hubs, but may be used in other situations.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in both the figures.

Figure 1 is a sectional elevation of a wagon hub and axle, showing myinvention applied thereto; and Fig. 2 is a persp ctive View of the oilerremoved from the hub.

The invention will first be described in connection with the drawings,and then pointed out in the claims.

A represents the hub; B, the axle, and O ,the oil box or cup fitted inopening D, made in the hub.

The oil-cup comprises a main body formed with an oil-chamberb and bottomaperture 0, through which the oil passes from the chamber to the axle.The exterior of the main body is in three diameters and formed with asmany sets of screw-threads viz., the screwthreads (Z to screw into thehub, the intermediate screw-threads d to receive the outer cap E, andthe upper screw-threads d to re- Serial No. 347,597.

ceive the inner cap F. Between the screwthreads d d the body is madepolygonal, as at (Z to adapt the cup to be screwed to place by means ofa wrench. The lower end of the main body is reduced, as shown at e, andcurved to form the lips e e, which come in contact with the axle andprevent clogging of the orifice c.

In the inner cap F is fitted a screw-rodf, the point of which is adaptedto close more or less or wholly the apertures c, and this rod isscrew-threaded, and by turning it in or out the flow of oil from theoil-chamber to the axle may be regulated, as desired.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- 1. The main body formed with an oil-chamberand orifice c and having its exterior formed with screw-threads d d d incombination with the inner and outer caps and the screw-rod f toregulate the flow of oil, sub stantially as described.

2. The main body formed with an oil-chamber and an orifice c and formedwith the tips 6' at the lower end and screw-threaded at (Z d (1 incombination with the screw-caps E F and the screw-rod), fitted in theinner cap, substantially as described.
